WATCH ABOVE: A Dartmouth company is celebrating a recent investment of nearly $2.5 million investment from the federal government. On Friday, the company showed off its new knee brace, something it calls a world's first. Global's Steve Silva explains.

“The investment from ACAO will help us build a human-factors testing lab to accelerate our research and development process to test our product,” said Chris Cowper-Smith, the company’s CEO, at an event for the announcement.

“I had very low confidence walking around in public because I was scared I was going to fall and stuff like that but, since I’ve had the braces, I haven’t fallen since, so the biggest thing the braces have done for me is giving me my confidence back,” Grover-Murray said.

The federal government partnered with the company during the start-up phase.

“Repayment of the contribution made to Spring Loaded Technology Inc. will be based on the project achieving certain success factors or milestones, as per the contribution agreement signed by the Agency and the company,” Alex Smith, the director of communications and outreach for ACOA, said in a statement.

What those “certain success factors or milestones” entail are not being made public.
